' IMPRVEMENT IN OIL-SQUEEZERS.

Specification ferming part of Letters Patent No. 174,971, dated March21, 1876; application filed February 17, 1876.

To all whom 'it may concern Be it known that I, HANS OLsEN, of the cityof Montreal, county of Hochelega, Province of Quebec, Dominion iofCanada, have invented certain new and usefullmprovements inOil-Squeezers, of which I hereby declare the following specilication tobe a full, clear, and exact description, and will enableanyone skilledin the-art to make and construct the same.

My improvement is designed t0 take the place of the -horse-hair bag,which is,I believe, the only article now in use for the purpose ofextracting' the oil from seeds. I claim various advantages for mysqueezer over that of the ordinary horse-hair bag. First, I can producetwenty per cent. more oil from the same amount ot' seed. Secondly,- theseed, after the oil is extracted; is left in a better shape formarketable purposes. Thirdly, it is less likely to get out of order, andis therefore more durable. Fourthly, the pressure is more direct, andthere is-"no chance to expand at the sides, therefore much time issaved. Fif'thly, it is much4 easier to handle; and, sixthly, it ischeaper.

I will now proceed t'o describe itsconstruction, which is simple. Itiscprnposedot' wood, iron, and zinc or tin. My object is to constructtwo tlat pressingsurfaces, which shall tightly incase the seed to beoperated upon between them,rand at the same time yield suicient to allowthe oil thereby extracted to pass out without the pressure injuring thesides of the squeezer, which represents the pressing-surfaces. To betterdescribe my invention, I will have recourse to the drawing appended,which I desire to be taken as and form a part ot" this specification.

Figure l represents the face of one of the sides ot' the squeezers; Fig.2, the exterior of the two sides, and Fig. 3 a side view ot' thesqueezer.

A represents strips of wood, which should be sufliciently hard andtenacious to stand the heavy pressure brought to bear upon it withoutsplitting. They f should be so cut that when laid side by side they willpresenta surface which shall taper toward one end. I

`any other suitable metal.

desire to have it understood, however, that I do not ecnne myself to anyparticular shape or form; but the one I shall describe I find to be thebest for all practical purposes. Through these strips of wood I runthree iron rods, f, which at the smaller or tapering end ofthe squeezerare secured by rivets d, or by hammering their ends un til they are heldin place.

when they are held securely by the rods f, are

secured plates E, of corrugated zinc, tin, or This metal forms the inneror direct pressing-surface, and is secured to the wood by nailing atintervals. To each side of the squeezers surfaces braided strips ofhorse-hair are attached, being secured by horse-hair thongs, which arepegged into the wood, being held the same as bristles in a brush. Anyother suitable means may be employed. The object of this horse-hairbraid is to keep the seed to be operated on in place between thepressing-surfaces of the squeezer, and being porous too, at the sametime, allow the oil to pass out freely. The two sides of the squeezer,as represented in Fig. 2, are secured together by the leather hinge B.The end ofthe sq'ueezer, where the hinge B is located, is provided withan iron or a metal handle, C, which renders the squeezer more easilyhandled.

Having thus described the construction of my squeezer, l will nowproceed to describe its practical operation Ihe seed to be operated ouis placed between the two sides A, provided with zinc or tin linings,care being taken that only sufcient is introduced to allow of thesqueezer being closed when under pressure, so that the edges of thehorse-hair braids shall be close to each other, or sufficiently sotto,prevent the seeds oozing out. The 'squeezer isthen introduced under themetal E, horse-hair braids G, rods f, strips L, metal strips I, andhandle C, the whole arranged and constructed substantially as and forthe purposes specified.

In testimony that I claim the foregoing as my own invention, I havehereunto signed my name in the presen-ce of two witnesses.

HANS OLSEN.
